Improvement in curtain-fixtures



JOHN Hf WILHELM, or oH'LoAco, `1LLINo1s.

Letters Patent No. 109,087, daad-November s, 187e The Schedule referredto in these LettersA Patent and making part of the same.

To all whom. it may concern Be it known am I, JOHN H. wltnnmf, -of cincago, m the county of Cook and State h of Illinois, have invented anImproved Curtain-Fixture and I dohereby declare that the following is. afull and exact descriptionl thereof, which will' enable those skilled inthe art to make and use the same, reference being had to theaccompanying drawing and letters marked thereon making a part ot' thisspecification,'in which Figure l is an elevation ol' a u'hnlow-l'raniewith my curtainxture attached.

Figure 2, a longitudinal central section of the roller and brackets,with detailed views.

Figure 3, an elevation of a wilnlow-fran|e with the bracket-s fastenedto the jamb-casings.

Figure 4, a perspective view of the movable washer, against whichthospring operates .in raising and lowering the curtain, and in holdingitin position.

Figure 5, aperspectivc view ofthe imbedded washer and tube-guide.

Figure 6 represents thc weight attached to the betteln of the curtain orshade.

Figure 7 shows the slot in the bracket for the more convenient receptionot'thejournal ofthe roller.

rlhe object of this invention is toprovidc an adjustable whnlow-curtainfixture, adapted not only to windows of diii`erent widths, but also tothose of' different heights; andv Its nature consists in a device forremoving the pressure of the spring that holds the Vcurtain in position,and in thc combination and arrangement oi' parts, as hereinafter morefully described.

Figs. 1 and 2 represent a wooden roller, with the journal 1t andspool-collar plate l similar to the same parts in my curtain-fixturepatented July 2G, 1870.

The bracket B with the central. socket L, and the bracket E with thecord-guard J, are also similar in all respects to the same parts in mycui't-ain-xtui'e for which Letters Pat-ent have been granted bearing theabove date, with the exception of the orifice K in the bracket B, andthe ordinary slot S in the bracket E.

H, iig. 2, represents a metallic tube, having a slot, L', and, when madeas a casting, it is more convenient to cast it in two separate pieces.

The corresponding parts W \V, when put together and inclosed within thecylindrical spiral spring l, form the tube H with the slot L.

The tube H may be made ot' any suitable metallic substance, and in twoparts, or asone single tube.

J, figs. 2 and 4, represents a movable washer, with a cross-bar, N, anda hole on each side of N to admit the parts W l or prongs of the tube H.

The projections n n are designed to prevent the spring I from slippingbetween the tube H and the washer J. y

\Vhen the spring-I is suiiiciently'large to obviate this difficulty bymeans of its thickness, the projections n n' may with advantage beomitted.

l.he cord C is fastened to the cross-bar N.

K is an orifice through the central part of the socket L in bracket B,iig. 2, through which the cord G passes.

1l, iig. 5, is a single casting, answering the purpose both of a washerand tube-guide, andis inserted in the hole G bored in the large end ofthe roller after it has been properly adjusted to the width of thewindow.

P is a slot, designed to receive a bent implement or wire for thepurpose of drawing out P when necessary.

lhe movable washer J, 2, 'operates against the spring I on the tube H,and against the imbedded washer and tube-guide I), lig. 5.

Q', tig. 6, represents a weight attached to the slat Q, or to the bottomof the curtain or shade.

@ne or more weights may be thus attached when necessary.

Q may be dispensed with when the weight of the curtain is itselfsutlicient to cause it to unroll on removing the pressure. from thespring I by pulling the cord U. I

The cord C, with the device to which it is attached, is designed tolower the curtain when the window is so high that the curtaintwhen drawnup by means of the cord l), cannot be conveniently reached by the hand.

By pulling the cord C the curtain A may be lowered to any desired point.p

Then the curtain is so heavy as to require the spring I to be of greaterstrength than usual, it may be drawn up more easily by, at the sametime, while pulling the cord'D also pulling the cord IG, so as to Yremove the pressure of the spring I.

,By the same process, managing both cords at once, the operating of theroller Ennay be Vmade almost or entirely noisel'css.

Having described my invention,

XVhat I claim, and desire to secure by Let-ters Pat-1 l. Y The imbeddedwasher and tube-guide l in combination with the movable washer J, thetube H, the cylindrical helical spring I, the cord 0,' the bracket B,oriiice K, and` roller F, when all the parts are constructed andarranged to operate as herein described, and for the purpose set forth.

il. The imbedded washer and tube-guide P in com` bination witlrthemovable washer J, the tube H, the cylindrical helical spring I, the cord(i, the bracket B,

orifice K,u roller F, spool collar-plate T, bracket E, and

cord-gua1dV,wl1en all the parts are constructed' and arranged to operateas herein described, and for the purpose seb forth.

3. The imbedded washer and tube-guide P in conibination with the movablewasher J, the tube VH, the

cylindrical helical spring I, the cord C,

the bracket B, orifice K, roller F, spool collar-plate T, bracket E,

cord-guard V, and weight Q on the bottom of the fitnessesz GEORGE L.CHAPIN, E. E. GIBSON.
